How much microplastics is there in Swiss rivers and lakes?
How much microplastics is there in Swiss rivers and lakes?
Plastic particles less than five millimeters in size, also known as microplastics, often settle far away from their point of origin. researchers have now developed a model that can be used to calculate the concentration of microplastics in Swiss lakes and rivers. Every year, 14,000 tons of plastic end up in Swiss soils and waters, in part in the form of microplastics: Particles in the micro to millimeter range.

Black rhinos: horns or life!
Black rhinos: horns or life!
Pre-emptively decorating endangered black rhinos to protect them from poaching. A doctoral student in biology at the University of Neuchâtel (UniNE) has studied the impact of this measure on the animals' behavior in ten nature reserves in South Africa. Vanessa Duthé presents her analysis today in the leading scientific journal PNAS, as part of the Black Rhino Conservation Project she initiated .

Traces in the water
Traces in the water
How we are contaminating our waters with microplastics and a multitude of chemicals. A plastic sandwich wrapper bobs in the water where the Limmat River flows out of Lake Zurich. The current carries it downstream through Zurich's historic centre before eventually depositing it on the bank of Werd island.

Swiss energy system could be independent and carbon-neutral by 2050
Swiss energy system could be independent and carbon-neutral by 2050
Researchers from EPFL and HES-SO Valais have modeled the Swiss energy system under the hypothetical constraints of carbon neutrality and energy independence by 2050. The results show that these two constraints could be met while reducing energy system costs by about 30% compared to 2020. A carbon-neutral and independent Swiss energy system in 2050 is theoretically achievable using the currently untapped local renewable energy resources.

Droughts increasingly reduce CO2 uptake in the tropics
Droughts increasingly reduce CO2 uptake in the tropics
Researchers have found that droughts and land water variability have had increasing effect on the carbon cycle in the tropics over the last sixty years. Most climate models fail to capture this observation. This could mean that terrestrial ecosystems could absorb less CO2 than expected in their role as carbon sinks in the future.

The fascinating vultures are back
The fascinating vultures are back
Not so long ago, seeing a griffon vulture in Switzerland was an extraordinary sight. For the past ten years, the species has been regularly crossing our skies.

Climpact: Flying, Fondue and CO2
Climpact: Flying, Fondue and CO2
Everything we do has a carbon footprint but are our perceptions of the emissions we generate on a daily basis aligned with reality? To find out, two researchers have launched Climpact a new tool to help separate fact from fiction. Whilst the environment, including our climate, came out as the main concern for Swiss people in 2022 , a global survey by the market research firm IPSOS has found that misconceptions are rife about the most effective climate solutions.

Countries would be well advised to assist each other with regard to gas
If European countries collaborate, they can avoid severe energy scarcity due to a gas shortage. This is the finding of a new study by researchers.

Plastic gobblers found in alpine and arctic soils
Plastic gobblers found in alpine and arctic soils
Scientists at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL have discovered microbes that degrade plastic at cool temperatures. This opens up new perspectives for recycling certain types of plastic. Most known microbes require at least 30°C for their decomposition work. Microorganisms are great hope for the development of a circular economy for plastics.

A survey of genetic diversity among native Swiss living organisms
A survey of genetic diversity among native Swiss living organisms
Switzerland is monitoring its biological diversity as part of a global effort to understand its changes and prevent further biodiversity loss. Researchers from ETH Zurich are working on a pioneering pilot study that includes the analysis of genetic diversity of native species. The world is not only suffering from a climate crisis but also from a biodiversity crisis.

Climate change leads to disproportionately high pollutant absorption
Climate change leads to disproportionately high pollutant absorption
Pesticides and other chemicals harm biodiversity, and climate change is also threatening many habitats. With his study, Eawag researcher Johannes Raths has shown that these two challenges for our society may even worsen. Amphipods absorbed pollutants faster as water temperatures rose. The researcher has received an award from the Society of Environmental Toxicology and Chemistry for his paper on the toxicokinetics of amphipods in combination with increased water temperatures.

New Eawag spin-off advises wastewater treatment plant
New Eawag spin-off advises wastewater treatment plant
Environmental engineer Wenzel Gruber and microbiologist Robert Niederdorfer - both Eawag postdocs - founded the spin-off Upwater together with two other partners at the beginning of November 2022. It offers measurements for wastewater treatment plants to support them in reducing process instabilities, greenhouse gas emissions as well as energy consumption.

Glacial melt threatens habitats of alpine river organisms
Glacial melt threatens habitats of alpine river organisms
Glacial melt affects numerous organisms that are native to streams fed by glacial water. As the ice masses increasingly retreat, the bodies of water warm up, threatening the habitats of their cold-water inhabitants. Researchers from Eawag, WSL and an international team have now found a method of identifying future potential refugia for these cold-water organisms.

DNA traces in groundwater
DNA traces in groundwater
May 3, 2023, An Eawag study shows that a large variety of living organisms leave their DNA traces in groundwater - which also depends on the land use in the catchment area. In future, these biological parameters could be used to assess groundwater quality. Groundwater is an invisible - and therefore often disregarded - treasure that is threatened worldwide due to overuse and pollution.

The inequalities of low-carbon electricity
The inequalities of low-carbon electricity
A team from the University of Geneva reveals how a low-carbon electricity sector could favour or disadvantage certain regions in Europe. Greenhouse gas reduction, new jobs, new investment opportunities: the benefits of decarbonising the electricity sector - one of the most polluting - are obvious. However, a transition to lower-carbon electricity production could have a negative impact on some regions, depending on their vulnerabilities and their capacity to adapt, while it could have a positive impact on others.

Circuit boards from renewable raw materials
Circuit boards from renewable raw materials
Can ecologically sustainable circuit boards for the electronics industry be produced from cellulose fibers? Empa researcher Thomas Geiger looked into this question. He is now part of a multinational EU project called Hypelignum". Its goal: biodegradable electronics. For many years, Thomas Geiger has been conducting research in the field of cellulose fibrils - fine fibers that can be produced from wood pulp or agricultural waste, for example.

Improving the microbial quality of recycled water in Bengaluru
Improving the microbial quality of recycled water in Bengaluru
In urban India, rising water scarcity and increasing pressure on water supply utilities have prompted the use of treated wastewater as an alternative source. A study of Eawag together with Indian partners explains how the use of sensors and automated chlorination can improve microbial water quality in on-site water reuse systems for increased user safety.
